T-Code: MMPI – from Tool Bar select – System – User Profile – Own Data – In parameter Tab Enter “MMPI_READ_NOTE” in parameter Field
Then, Remove assignment of Plants from Company Code (In SPRO).
Now use T-Code OMSY & Set the required Period.
Re-assign Plants to Company Code & Check whether correct period is open thru T-Code – MMRV
Now use T-code – OMWD to Assign Valuation grouping code to Valuation area because the earlier data gets deleted when assignment of Plants was removed.
Use the transaction code OMS2 then select FERT (for Finished Goods) or any required Material type & then click on the Quantity and Value update.
Select your plant or valuation area and put Tick Marks in Value update and Quantity update
Hope this helps,
